Improved protection performance and durabilityThe coating of the filter is not permanent. It gets a damage repeatedly when we clean it with wipes and gets weak as time passes by. The filter can protect the lens from physical damage, but the coating receives the strike first as scratch. When a coating of a filter is solid and scratch resistant, it will be a great advantage.This is designed with ultra-hard nano coating to protect your camera lens. The HD nano Mk II UV filter is a filter with a UV cut curve that does not affect the visible light range. In addition this filter features a new powered coating that protects the lens from scouring, while allowing easy cleaning of water spots and fingerprints. The HD nano Mk II glass is 4x stronger chemically enhanced optical glass.Designed to protect a camera's expensive lens system from scratches and impact, HD nano Mk II filter is essential gear for photography under extremely severe conditions.Powered coatingNewly developed coating is stuck to the glass surface more firmly and closely by the nano level than formerly. Due to this, the particles are layered on the glass surface with extremely high density that creates a hard and smooth coating. Besides ultra-hard and smooth features, HOYA HD nano Mk II coating has superior water and oil repellent abilities that will make filter maintenance easy and stress free.Hardened glassHardened optical glass that has 4 times the breaking strength. New 32 layer (both sides) ultra-smooth, ultra-hard nano coating Stain resistant, water & oil repellent coating makes everyday maintenance easier Ultra-hard surface coating is 800% more scratch resistant than general coating High Density Sharp Cut UV glass Chemically Enhanced Optical Glass is 4x Stronger than usual optical glass Very Thin Frame, Front thread to attach lens caps and other filters Press mount technology holds glass securely The HD nano Mk II filter that not only the hardened glass but also the ultra-hard nano coating protects your lens solidly under the severe conditions.

HOYA Variable Density II is a density adjustable filter with an ND range from 1.5 to 9 f-stops (ND3-400). The difference with the previous HOYA Variable Density filter is the newly designed rotatable frame with convenient knob, allowing for better operation.Variable density filters are widely used because they can replace a set of solid ND filters by providing a range density that can be adjusted according to the desired exposure settings. In still shooting, variable density filters lower the shutter speed according to the photographer’s intentions when the shutter speed cannot be lowed due to camera limits. Variable density filters can also increase the amount of boke when shooting in the over-lit conditions, thus, preventing the image from overexposure.In video shooting, it is fundamental to keep the shutter speed fitting the frame rate setting. That is, to keep it equal to double the frame rate for optimal results. This is because, unlike still photography, an excessively fast shutter speed may create a jarring effect and produce afterimages that will not look good in the final video.By using variable density filters, the shutter speed can be adjusted to the proper value to get that natural and smooth looking motion requested in video footages.Be aware that when the filter is attached to the lens, the lens cap size becomes one size bigger. So if your lens has a filter thread size of 77mm, you will require an 82mm lens cap. The widened front filter frame has been designed on purpose to avoid vignetting.
